High frequency signal booster in radio frequency circuit

A radio frequency (RF) circuitry comprising:

• one or more transceivers respectively coupled to one or more antennas to transmit or receive RF signals, wherein each of the one or more transceivers is configured to convert between the RF signals and baseband signals based in part on a high frequency signal;
• and
• a signal booster coupled to the one or more transceivers to provide the high frequency signal based on a local oscillator signal received via a transmission line, the signal booster comprising a pair of transistors each comprising a respective gate, drain, and source, wherein the pair of transistors are cross-coupled each other in cascode so that:
• drains/sources of the pair of transistors are coupled respectively to a first output terminal and a second output terminal of the signal booster, the first output terminal and the second output terminal configured to provide the high frequency signal;
• sources/drains of the pair of transistors are coupled respectively to a first line and a second line of the transmission line to receive the local oscillator signal;
• and
• gates of the pair of transistors are cross-coupled respectively to the second output terminal and the first output terminal.

A high frequency signal booster for use in a wireless transceiver, the signal booster comprising an amplifier comprising:

• a pair of transistors each comprising a respective gate, drain, and source, wherein the pair of transistors are cross-coupled each other in cascode so that:
• sources/drains of the pair of transistors are coupled to a transmission line to receive a local oscillator signal;
• drains/sources of the pair of transistors are coupled to an output terminal configured to provide a boosted high frequency signal based on the local oscillator signal;
• and
• gates of the pair of transistors are cross-coupled respectively to the second output terminal and the first output terminal.
